Lots if people know crypto currency and its importance. There are lots of jobless are being helped by this and so those who have jobs too. It really is helpful to us.
You can earn money with cryptocurrencies but that is not its main function and since it is likely you are talking about bounties I really think that we are reaching a saturation point, too many people are trying to earn money out of bounties and more scams are appearing which means that the share of legitimate projects to participate is going down and more people are just wasting their time getting tokens that have no value.
